Problems solved by technology
[0002] It is very difficult to install wheels on the assembly line of heavy mining dump trucks. The reasons are: 1) the weight of the wheels is large, and the weight of a single wheel is 6.25t; 2) the size is large, with a diameter of 3650mm and a thickness of 1254mm; 3) strict production cycle requirements: the installation time of a single wheel Within 15 minutes; 4) The outer contour of the wheel and tire is spherical, so it is difficult to locate
[0003] In the past, heavy-duty mining dump truck wheels were mostly installed on-line with cranes and auxiliary equipment. The disadvantages are: 1) high labor costs, usually requiring 6 installation workers; 2) difficult control of the installation cycle; 3) labor-intensive workers; 4 ) poor consistency of installation quality

The invention provides a six-freedom-degree swing frame type wheel assembling machine which comprises drive wheel systems, a vehicle body system, a left swing frame system, a right swing frame system,an electric control system and a hydraulic station. A U-shaped vehicle body in the vehicle body system is connected with connecting plates in the drive wheel systems. A first hinge and a second hingeof the vehicle body system are connected with a first overhanging beam in the left swing frame system and a second overhanging frame in the right swing frame system correspondingly. The electric control system and the hydraulic station are installed in the U-shaped vehicle body. The wheel assembling machine comprises six freedom degrees including moving in the axis direction of wheels, moving inthe direction perpendicular to the axis, spot turning, rotation around wheels and front-back pitching swinging of the wheels. By means of the six-freedom-degree swing frame type wheel assembling machine, assembling mechanization of wheels of heavy mining dump trucks can be achieved, the labor cost is reduced, and the labor intensity of workers is lowered; and the assembling efficiency of the wheels of the heavy mining dump trucks is improved, and the installation quality consistency and the production takt are ensured.
Description
technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to a six-degree-of-freedom pendulum type wheel assembly machine and an assembly method thereof. Background technique [0002] It is very difficult to install wheels on the assembly line of heavy mining dump trucks. The reasons are: 1) the weight of the wheels is large, and the weight of a single wheel is 6.25t; 2) the size is large, with a diameter of 3650mm and a thickness of 1254mm; 3) strict production cycle requirements: the installation time of a single wheel Within 15 minutes; 4) The outer contour of the wheel and tire is spherical, which makes positioning difficult. [0003] In the past, heavy-duty mining dump truck wheels were mostly installed online with cranes and auxiliary equipment. The disadvantages are: 1) High labor costs, usually requiring 6 installation workers; 2) It is difficult to control the installation cycle; 3) The labor intensity of workers is ...
